The new DriveWizard Industrial® will support all industrial 1000 series drives as well as P7, F7, G7, and G5 drives. It will not support the 7 series of microdrives (they are obsolete), and it will not support the commercial drive products.

Installing Parker's InteractX software will remove the licensing. Do the following to recover:1. Navigate to where the Yaskawa MotionWorks IEC software is installed (usually C:\Program Files\YaskawaMotionWorks IEC Pro).2. Run the SETUPEX.EXE file by double clicking on it.3. Reboot the computer.MotionWorks IEC should be able to run again.

When Pn002.2 (Absolute Encoder Usage) = 0 (Use the absolute encoder as absolute encoder) the SERVOPACK is not ready to accept the /S-ON (Servo ON) signal until the SEN (Absolute Data Request) signal is ON. The SEN signal can be masked ON by setting Pn515.0 = 7 (The signal is always active).

Why is the SGMVV motor's cooling fan stopped after only a few minutes of running?

Posted Date: 08/20/2013

Answer:

The 3-phase AC power to the fan is incorrectly wired. L1, L2, L3 of the 3-phase AC input to the fan must be in the correct sequence, otherwise the fan will be running backwards which causes the fan motor to overheat and trips its internal thermal protector causing the fan to shutdown. Check the L1, L2, L3 wiring, and check the airflow of the fan to ensure it is blowing in the direction of the indication arrow marked on its housing. Correct the L1, L2, L3 wiring if necessary.This also applies to SGMVH motor's cooling fan.

The power consumed by a VFD always equals the power output of a VFD plus the internal drive losses. When the drive is running at frequencies below the line power frequency (usually 60Hz), the output voltage from the VFD is below the line voltage, and therefore the output current must be higher than the input current.

One common cause of the CPU load being higher than expected is caused by using a custom Function Block that uses a large structure connected as a VAR_INPUT instead of a VAR_IN_OUT.

When a variable is declared as a VAR_INPUT, the MPiec Controller copies the entire contents of the structure into the Function Block every scan. Other programming languages refer to this technique as “Passing by Value.” In this situation, the Function Block does not have the ability to alter the contents of the original data. When declaring a variable as VAR_IN_OUT, the MPiec Controller passes a pointer to the original location of the variable rather than a copy of the data. Other programming languages refer to this technique as “Passing by Reference.” The pointer is an internal 32 bit value, which is significantly more efficient than copying the entire contents every scan. This method also gives the Function Block the ability to alter the contents of the structure variable.

To show this example in practice, the attached document shows two scenarios. The first scenario scans a Function Block with a large structure as a VAR_INPUT and results in a high CPU load. The other scenario shows the same structure as a VAR_IN_OUT and has no impact on the CPU load.

The large structure is an array of an array creating 500,000 LREAL’s. There is nothing else in the program, the custom Function Blocks have no code.

Why is a reboot required after sending an Axis Configuration from LogicWorks to a SigmaLogic axis?

Posted Date: 09/12/2014

Answer:

Some of the configuration files in the SigmaLogic are only read at power-up. These files contain information about the scale factors, servopack parameters and other configuration options of the built-in controller.

The encoder battery used with the ServoPacks (JZSP-BA01) is required if a multi-turn absolute encoder is needed because it holds the multi-turn encoder data when the drive power is down. Therefore, when setting the drive to use the absolute encoder as an incremental encoder or a single-turn absolute encoder, the encoder battery is not needed. The encoder battery power can be applied via the battery case on the ABS encoder cable (CN2), or through the I/O connector (CN1, for example Sigma7 ML-III ServoPack, pins 14[+] & 15[-]).

Figure1

When using an absolute encoder without the encoder battery case, the battery can be connected to through CN1 connector on the ServoPack:

Figure2

Figure3

The Absolute Encoder Current Draw specification is:

20 μA when ServoPack is powered off

3 μA when ServoPack is powered on (w/o diode in place)

To determine the worst case battery life, divide the A-hour rating of the battery by the Sum of the current of all encoders when powered off.

The other type of batteries is used for the MP controllers. These batteries (JEPMC-BA3001) provide a backup power for the CPU non-volatile memory, preserving the SRAM data when CPU power is down. This data includes the retained variables, the alarm history, the absolute encoder offset and the real-time clock data. The SRAM can last for one hour without the battery connected. This battery must be replaced while power is supplied, within 2 weeks of when the BAT indicator first lights. For the MP2600, the SRAM battery power can be applied through the battery connector (CN14), or through the I/O connector (CN13 pins 7[+] & 32[-]).

Why does Vipa remote I/O fail to update when it has a connection status of 0x1000 (connected) or 0x320 (deleted configuration)?

Posted Date: 09/05/2017

Answer:

If the Vipa Ethernet coupler was previously configured and then modules are added or changed, you must perform an online save through its web page before they will function correctly. If the new configuration is not saved, the Vipa Ethernet coupler will flash the SF and MS red LED’s when the controller connects. The I/O status variable in the MotionWorks IEC project will show a status of 0x1000 (connected) or 0x320 (deleted configuration) but the I/O will not update.

To save the configuration on the Vipa Ethernet coupler:

Open the Vipa web page by typing the IP address into the browser’s address bar.

After saving the configuration, the Vipa Ethernet coupler must be powered down for at least 20 seconds, and then powered back up. If the power is short cycled, the Vipa Ethernet coupler will not power up.

See attached document for a screen shot of the web page’s Configuration tab

Some parameters set in the SigmaLogic servopack require a logical power cycle to become active. If the configuration has changed, particularly those values set in the Configure – Options section of LogicWorks, another reboot will be required before the new settings will take effect.

Part of the SigmaLogic Embedded Software boot up sequence compares the actual servopack parameters to the desired configuration. If there is a mismatch, the desired parameters are sent to the servopack and an automatic reboot is triggered. The new parameters actually take effect after this second reboot.

Why does the SGDV not recognize the functional safety module attached to the SERVOPACK?

Posted Date: 03/02/2015

Answer:

The CN-8 (Hardware BaseBlock) jumper must be removed from the SERVOPACK before the functional safety module is recognized. The CN-8 connector must remain unconnected for the function safety module to operate properly.

1) The MP-940 24VDC is not connected, or the polarity of the power is reversed 2) The internal protection fuse (FU1) inside the MP-940 has been blown. (Attached please find the fuse specifications, 1.5A required, Cautionary Note: Field replacement of this field could void warranty)3) The 24VDC power supply could be undersized, and inrush could causes a device to drop out. Keep the following specifications in mind when sizing the power supply:Continuous power consumption:MP-940 control power 0.4A SGDH (400V) control power 1.0A (3.0A surge for 50msec) (DC motor brakes should be powered by a separate supply to reduce noise)

4) If the MP-940 and SGDH are powered up together and successfuly synchronize but the SGDH subsequently loses control power and has it reapplied while the MP-940 24VDC remains constant, bb will blink.

5) If the MP-940 has been without power for over 24 hours without a backup battery attached, or the program is stored in flash.

Why does the Servopack display an AF1 alarm when main power is removed? None of the solutions in the User's manual remedy the problem.

Posted Date: 07/13/2004

Answer:

A.F1 (AF1) alarm is an open phase error.

Two potential external causes:

1) One or more of the contactor contacts are sticking and causing one or two phases to stay connected when they should open.Solution: Replace/Clean contacts (if serviceable), or replace contactor.

2) Another possible cause: A power line filter has been improperly installed between the contactor and the ServoPack. The three phase power line filter discharges unequally and it appears to the ServoPack that there is an open phase.Solution: Install power line filters properly, prior to the contactors in the electrical circuit. (Reference Section 3.1 in Sigma II User's Manual [YEA-SIA-S800-32.2] for wiring specifications)
